A data line driver includes a counter, a data converter, a gray-scale voltage generating circuit, multiple voltage selectors and multiple output circuits. Each voltage selector receives n voltages generated by the gray-scale voltage generating circuit. The voltage selector includes: n switches; a capacitor which holds electric charges; and a selector which generates n control signals to control ON and OFF of the n switches, respectively. The voltage selector selects two voltages out of the n voltages, and makes a control signal variable which is inputted into one of switches to which the two voltages are respectively applied. Thereby, the voltage selector generates k intermediate voltages, and outputs the n voltages and the k intermediate voltages.
